Unexpected starting of actuator!
When using automatic deblocking with level-controlled operation command evaluation,
unexpected starting of actuator into the wrong direction might occur when trying to
eliminate a double-sided torque fault (torque faults in directions OPEN and CLOSE
are present at the same time).
Use automatic deblocking only in combination with edge controlled operation
command evaluation (parameter Com. eval. REMOTE M1709).
In case of torque switch tripping in intermediate position (i.e. prior to reaching the
end position), the actuator automatically attempts to reach the end position by
operation into the opposite direction and executing the actual operation command
once again.
The torque fault signal is suppressed during automatic deblocking. Should torque
switching trip again once automatic deblocking is complete, the actuator is switched
off and actuator controls signal a torque fault.
